# Rust program to convert a decimal number to a binary number

Here, we are going to learn how to convert a decimal number to a binary number in Rust programming language?

Problem Solution:

Here, we will create a 16-bit integer number and then print the corresponding binary number.

Program/Source Code:

The source code to convert a decimal number to a binary number is given below. The given program is compiled and executed successfully.

```// Rust program to convert decimal number
// to binary number

fn main() {
let mut num:i16 = 14;
let mut cnt:i16 = 15;
let mut tmp:i16 = 0;

println!("Decimal Number: {}",num);
print!("Binary Number: ");
while cnt>=0
{
tmp = num & (1<<cnt);
if tmp>0
{
print!("1");
}
else
{
print!("0");
}
cnt = cnt - 1;
}
}
```

Output:

```Decimal Number: 14
Binary Number: 0000000000001110
```

Explanation:

Here, we created an integer variable num with an initial value of 14. Then we used bitwise operators to print the corresponding binary number.
